How to include vendor-specific option 17 suboptions 11, 12 and 13 in DHCPv6 solicit/request using dhclient

Question

My request is to include option 17 sub-options 11, 12 and 13 in DHCPv6 solicit/request and I configured the same in dhclient6.conf on my Ubuntu as below.

send dhcp6.vendor-opts 00:00:0d:e9:00:0b:00:06:42:44:56:45:52:30:00:0c:00:03:6c:61:6e:00:0d:00:06:76:61:61:75:61:39;

From packet trace I can see option 17 in solicit/request but sub-options are not proper and I guess not encapsulated.

Output snippet from tshark:

Vendor-specific Information

        Option code: 13
        Option length: 6
        Option data: 766161756139

Can someone please help me on how to include sub-options in a correct format.

What I tried so far:

1. Went through the RFC and configured as per the format by including option_code and option_len but got malformed packet.
2. Referred similar type of question and configured option-17 sub-option 2 which is absolutely fine but problem occurs with sub-options 11, 12 and 13.

Any help would be appreciated.
